4.0 ELECTRIC SYSTEM
4.1 IMPORTANT INFORMATION
The type of battery used in a Columbia vehicle has a service requirement which is quite different from that
of an automotive battery.
The electric vehicle battery supplies all of the power to drive the vehicle. During operation the power
stored in the batteries is expended. While the amperage drain rate can vary greatly depending on the
type of service, the duration of use and the number of "starts" and "stops" made during a day, the
batteries nevertheless progress through each duty cycle from "fully charged" to an almost depleted state.
This type of service is known as "deep cycle" service and electric vehicle batteries are specifically
designed to handle this type of service.
Proper performance of your Columbia Vehicle can only be obtained from specified deep cycle, electric
vehicle batteries.
PLEASE REVIEW IMPORTANT DANGER STATEMENTS WHEN WORKING AROUND BATTERIES
AND CHARGING SYSTEMS!
Always remove key and disconnect batteries before servicing or repairing the vehicle (Section
2.6).
Always wear full-face shield when working on or near batteries.
All batteries used in electric vehicles can explode! Batteries produce explosive hydrogen gas at
all times, especially, during charging or discharging. Ventilate area when charging batteries.
Do not attempt to charge a battery if it is frozen, or if the case is bulged excessively. Frozen
batteries can explode!
Properly dispose of the battery.
Do not smoke around batteries. Keep sparks and flames away from batteries and the charging
area.
When working around or servicing batteries use care to prevent an accidental arc which could
cause an explosion.
Use only approved insulated tools, remove jewelry such as rings, watches, chains etc. and
place an insulating material (wood, plastic, rubber etc.) over all battery connections.
If any problems are found during scheduled maintenance or inspections, do not operate vehicle
until repairs are made.
Failure to make necessary repairs could result in fire, property damage, severe personal injury,
or death.
Battery acid is poisonous and can cause severe burns. Avoid contact with skin, eyes, or
clothing.
ANTIDOTES
EXTERNAL: Flush with water. Call a physician immediately.
INTERNAL: Drink large quantities of milk or water. Follow with milk of magnesia or vegetable
oil. Call a physician immediately
EYES: Flush with water for fifteen minutes. Call physician immediately.
4-1
NOTICE: Automotive batteries should never be used for "deep cycle" application, as their
useful life will be very short.
Install surge arrestors on incoming AC power lines. Surge arrestors will help protect
electrical/electronic components in the charger and vehicle from all but direct or “close
proximity” lightning strikes.
Damaged or corroded battery terminals should be replaced or cleaned as necessary. Failure to
do so may cause overheating during operation.
Do not attempt to recharge batteries with a charger not designed for your vehicle.
Only trained technicians should service the CR-10 charger. Contact your Columbia Dealer for
assistance.
4.2 BATTERY INSPECTION & MAINTENANCE
Check the electrolyte level on new batteries before they are put into service, and, at a minimum, once a
week thereafter. Water use increases as batteries age.
See Figure 4.2.1. Never allow the electrolyte level (A) to fall below the top of the plates (C). If the plates
are exposed, add only enough to cover the plates before charging. After batteries are fully charged, fill
cells to just below the bottom of the cell vents (B). Electrolyte level should not touch the bottom of the cell
vents.
Do not overfill batteries. Electrolyte expands and can overflow during charging. Water added to replace
the spillage dilutes the electrolyte and reduces its specific gravity.
Use only distilled water. Vehicle batteries may use up to 16 quarts of water during their useful life and
non-distilled water may contain harmful minerals which will have a cumulative adverse effect on battery
performance and life.
Batteries and connections must be clean and dry. See Section 4.3.
Be sure battery hold downs are properly tightened. A loose hold down may allow the battery to become
damaged from vibration or jarring. A hold down that is too tight may buckle or crack the battery case.
Weekly inspect battery posts, clamps and cables for breakage, loose connections and corrosion. Replace
any that are damaged. Check to see that battery cap vent holes are clear. Plugged vent holes will not
permit gas to escape from the cell and could result in battery damage.
4-2
Figure 4.2.1
4.3 BATTERY CLEANING
Acid-soaked dirt on the battery terminal connections causes current leakage, reduces battery efficiency,
and battery life.
Check that all vent caps are tightly in place before washing.
Hose wash battery terminal connections periodically with clean low-pressure water to keep them free of
acid spillage, dirt, and other debris. Do not hose wash switches, solenoids and other electrical control
devices. Cover as necessary to prevent splashing.
Clean battery terminal connections with baking soda (sodium bicarbonate) and water solution (5
teaspoons baking soda per quart water) and stiff bristle brush. Rinse with clean water and dry with a
clean cloth. Do not allow solution to enter cap vent holes.
NOTICE: Follow local ordinances and codes for proper disposal of battery cleaning waste.
4.4 CONDITIONS WHICH AFFECT CHARGING
Always schedule enough charging time to allow the batteries to become fully charged. Charging time is
affected by age and battery condition, state of discharge, electrolyte temperature, AC line voltage, and
other variables. Correct charging methods extend battery life and vehicle range between charges.
New batteries need up to four hours more charging than “mature” batteries. Before the first use,
completely charge new batteries. Charging time will vary based on conditions noted above but will
probably be 6 to 10 hours.
If vehicle is used only occasionally, a refresher charge should be given prior to using.
Battery efficiency is affected by temperature. If the temperature of the outside air and/or batteries is
below 60º F, battery capacity is reduced. Batteries will require more frequent and longer charge periods in
early spring, fall and winter.
As batteries age, they finish charge at progressively higher charge rates and tend to use more distilled
water. At this point in battery age, charger will automatically begin reducing charge time.
Batteries found defective must be replaced. All batteries in a vehicle should be matched according to age,
capacity and brand.
4.5 BATTERY CHARGING
4.5.1 CHARGER INFORMATION
The built-in battery charger is custom made for Columbia vehicle CR-10 Models. Its operation is totally
automatic. When connected to a 110 - 120 Volt AC power source, the charger's electronic timer will turn
the charger on. It determines and provides the energy necessary to return batteries to a fully charged
state, automatically shutting off when the batteries are fully charged. This occurs when each cell reaches
approximately 2.5 volts.
4.5.2 CHARGER OPERATING INSTRUCTIONS
Plug 120 volt AC supply cord into charger receptacle on charger panel. After a short time delay of
approximately 5 to 6 seconds, a RED light comes on indicating battery charging.
When the solid state circuitry senses that the batteries are fully charged, the RED light turns off and the
GREEN light turns on indicating that charging is complete.
The GREEN light will remain on until the AC cord is disconnected. At that point the light will turn off and
the charger will reset itself for the next charging cycle.
4-3
4.5.3 LOW BATTERY RESET SWITCH:
This is used if the batteries are heavily over discharged. When the AC cord is connected, the RED light
will turn on but will shortly turn off. To reactivate the charger, push the reset button for 10 seconds. This
will restart the charger. Release the button and the charger will continue to charge.

4.6 SPECIFIC GRAVITY TEST
It is possible to determine a battery's ability to perform by measuring the specific gravity (sp. gr.) of each
cell with a hydrometer. This is the best method to determine a defective battery.
The hydrometer readings indicate two things:
State of Charge - The amount of electrical power stored in the battery.
Condition - The ability of battery to store and deliver power.
NOTICE: Batteries should be fully charged before performing specific gravity tests to determine
battery condition. Hydrometer tests of batteries not fully charged are misleading and
inconclusive.
There are different type hydrometers. Carefully read and follow the instructions supplied with your
hydrometer.
4.7 TIPS FOR PROLONGING BATTERY LIFE
To prolong battery life, recharge batteries as soon as they become 20% or more discharged (less than
1.238 sp. gr.). Batteries may be recharged if vehicle has been driven 15 minutes or more since the
previous charge.
Do not allow batteries to fall below 80% discharge (1.098 sp. gr.). Deep discharging significantly reduces
battery life. Opportunity charging during breaks or shift change can be used to extend range but always
complete a full charge cycle at least once a day.
If the vehicle is not operated daily the Power keyswitch should be turned off. This will reduce power loss
on the batteries.
Batteries in storage may self discharge and should be recharged when the specific gravity falls below
1.238 sp. gr.
NOTICE: Specific gravity readings are at 80

F. Values need adjustment for electrolyte
temperature. Reduce .004 for every 10

5.1 MAINTENANCE GUIDELINES
To ensure that the vehicle is kept in a safe and correct operating condition, it must be inspected and
maintained on a regular basis. Proper lubrication, electrical control adjustments, safety feature checks,
etc. performed at recommended intervals will help prevent damage or failure of the unit while providing
optimum performance.
Follow the guidelines below to assure proper maintenance.
Allow only trained maintenance personnel to maintain, repair, and inspect the vehicle.
Before starting any repairs or maintenance, immobilize the vehicle by turning the power keyswitch off
and removing the key.
Disconnect both of the main battery pack leads before working on or disconnecting any electrical
component or wire.
Block the chassis with jack stands before working under a raised vehicle.
Conduct vehicle performance checks in an authorized area where a safe clearance exists.
Before starting the vehicle, follow the recommended safety procedures in Chapter 2, (SAFETY).
Avoid fire hazards and have fire protection equipment present in the work area.
Do not use flammable fluids for cleaning parts.
Work in a properly ventilated work area.
Regularly inspect and maintain in safe working condition the brakes, steering mechanisms, speed
and directional control mechanisms, warning devices, guards and safety devices.
Keep the vehicle in a clean condition to minimize fire hazards and facilitate detection of loose or
defective parts.
5.2 BRAKE SYSTEM
The mechanical brakes consist of two rear drum
brakes. With no force applied to the treadle, brakes
are properly adjusted when the back edge the treadle
is approximately even with the top edge of the rear
frame crossbar. See Figure 5.2.1.
To adjust the brakes (See Figure 5.2.2):
Loosen jam nut (Arrow A) on upper end of the
treadle to brake linkage.
Turn (lengthen) upper brake linkage (Arrow B)
and check adjustment.
Once properly adjusted and tighten the jam nut.
NOTICE: Minimum brake shoe lining thickness
is .080 inches.

5.2 CLEANING
Wash underside to remove all dirt and debris. Do not direct high pressure water at the speed switch or
tops of the batteries.
Wash body and seat with a mild detergent. Do not use abrasives (bodies are painted). Frequent washings
with mild soap will preserve the finish of your vehicle. For stubborn and imbedded dirt, a soft bristle brush
may be used. Tar, asphalt, creosote and the like should be removed immediately to prevent staining of
paint.
NOTICE: Do not use harsh detergents, abrasives or cleaning solvents that contain ammonia,
aromatic solvents or alkaline material to clean cab.
